Impact
A shadowy figure casting a wide net over a digital landscape filled with various devices such as computers, smartphones, and tablets. The net symbolizes the attacker's attempts to find vulnerabilities or use phishing techniques to gain unauthorized access.
A digital ladder extending upwards from a basic user icon towards a crown symbolizing administrative privileges. This represents the attacker's efforts to gain higher-level access within the system.
A chameleon blending into a digital background, with zeroes and ones flowing around it. This represents the attacker's ability to avoid detection by security measures, changing tactics to blend in with normal network traffic.
A thief with a lockpick toolkit working on a giant keyhole shaped like a login form, representing the attacker's efforts to steal user credentials to gain unauthorized access.
A magnifying glass moving over a digital map of a network, highlighting files, folders, and network connections. This image represents the phase where attackers explore the environment to understand the structure and where valuable data resides.
A series of interconnected nodes with a shadowy figure moving stealthily between them. This illustrates the attacker's movements within the network, seeking to gain control of additional systems or spread malware.
A large vacuum sucking up files, data icons, and folders into a bag held by a shadowy figure. This image symbolizes the process of gathering valuable data from the target network.
A command prompt window open in front of a digital background, with malicious code being typed out. This represents the phase where attackers execute their malicious payload within the compromised system.
A series of files being funneled through a covert channel out of a computer to a cloud labeled with a skull, symbolizing the unauthorized transfer of data to a location controlled by the attacker.
A cracked screen with a digital cityscape in chaos behind it, symbolizing the destructive impact of the cyberattack, such as service disruption, data destruction, or financial loss.
